Introduction

Quality assurance in the automotive industry leaves little room for error, especially when inspecting large assemblies such as oil pans and other aluminum or sheet metal components. Ensuring that these parts meet exact specifications presents a significant challenge, requiring precise and reliable measurement methods. This case study highlights how senswork’s ZScan® 3D multi-sensor system addresses these demands by delivering accurate three-dimensional measurements and enabling direct comparisons with CAD data.

Challenge

A key challenge was performing highly accurate 3D measurements on large aluminum assemblies without introducing shading effects that could compromise measurement quality. In addition to detecting general form deviations, the system also needed to identify subtle defects such as air bubbles and blisters, which can negatively impact the structural integrity and performance of automotive components.

Solution

To overcome these challenges, senswork implemented the ZScan® 3D multi-sensor system, which utilizes laser triangulation to deliver high-resolution, three-dimensional measurements of large assemblies. The system does not require spraying beforehand and performs precise inspections directly within the production cycle. It is capable of detecting fine surface defects, such as air bubbles and blisters, while simultaneously comparing measurement data against CAD models for comprehensive validation.
